I am trying to create the No Texting While Driving app in Chapter 4 of the AppInventor2 book and am having a problem. In the Text to speech portion, it shows using a JOIN block to string together a phrase and the phone number and a phrase and what the actual message is. However, in the text drawer where the JOIN block is, there is no JOIN block with four plug in slots, just two. I have joined a couple of JOIN blocks together (picture below) will this work or am I just missing something?
